measures of central tendency include all except: a. standard deviation b. median c. mean d. mode
The correct answer is (a) standard deviation. The measure of central tendency that is NOT included among the given options is the standard deviation (a).
Measures of central tendency are statistical measures that represent the central or average value of a dataset. They provide insight into the typical or central value around which the data tends to cluster. The three commonly used measures of central tendency are the mean, median, and mode.
a. Standard deviation is not a measure of central tendency. It is a measure of dispersion or variability in a dataset. It quantifies how spread out the data points are from the mean. Standard deviation provides information about the spread or scatter of the data rather than representing a central value.
b. Median is a measure of central tendency that represents the middle value in a dataset when the data points are arranged in ascending or descending order. It divides the data into two equal halves.
c. Mean is a measure of central tendency that represents the arithmetic average of a dataset. It is calculated by summing all the data points and dividing by the total number of observations.
d. Mode is a measure of central tendency that represents the most frequently occurring value or values in a dataset. It identifies the value(s) that appear(s) with the highest frequency.
Therefore, the standard deviation (a) is the measure of central tendency that is NOT included among the given options.

part a: an angle is two collinear rays with a common endpoint. find an example that contradicts this definition. how would you change the definition to make it more accurate? (5 points)
part b: give an example of an undefined term and how it pertains to angles. (5 points)
Part a: An example that contradicts it is when the two rays are not collinear.
Part b: An undefined term in geometry is "point," which is fundamental to understanding angles.
Part a: An example that contradicts the definition of an angle as two collinear rays with a common endpoint is when the two rays are not collinear. For instance, consider a scenario where two non-collinear rays diverge from a common endpoint. This contradicts the definition since collinearity requires the rays to lie on the same line.
To make the definition more accurate, we can modify it to state that an angle is formed by two non-collinear rays with a common endpoint. This revision ensures that the definition encompasses all possible angles.
Part b: An undefined term in geometry that pertains to angles is the concept of a "point." A point is a fundamental building block in geometry, representing a precise location in space without any dimension. When defining angles, points are used as endpoints for rays.
Without points, it would be impossible to determine the starting and ending positions of the rays, which are necessary for defining angles accurately. Therefore, the concept of a point is essential for understanding angles and their geometric properties.

First, convert these two mixed fractions into improper fractions.
You can do that by following these steps:
Multiply the outside number by the number in the denominator
Add the product to the number in the numerator
5\(\frac{1}{4}\) = \(\frac{21}{4}\)
3\(\frac{7}{8}\) = \(\frac{31}{8}\)
Now, convert these fractions so that they share the same denominator. 4 and 8 share the same factor of 8. Multiply the numerator and denominator of \(\frac{21}{4}\) by 2 so that the denominator becomes 8.
\(\frac{21}{4}\) = \(\frac{42}{8}\)
Now find how many inches of string each person has by using multiplication:
Sophie has \(\frac{42}{8}\) × 5 = \(\frac{210}{8}\) inches total
Cooper has \(\frac{31}{8}\) × 4 = \(\frac{124}{8}\) inches total
To find how much more inches Sophie has, subtract the two fraction from each other:
\(\frac{210}{8} - \frac{124}{8}\) = \(\frac{86}{8}\)
Simplify the fraction:
Sophie has 10\(\frac{6}{8}\) or 10\(\frac{3}{4}\) more inches than Cooper

Answer:
D: 2.67
Step-by-step explanation:
Assuming that both vertical lines are parallel, there are rules regarding angle sizes.
The rule that is specific to this question is alternate angles, this is when two angles are of the same size when they are on opposite sides of the line. This means that both equations equal each other:
10x + 13 = -3 + 16x
Add 3 to both sides to remove the negative 3 and isolate the 16x:
10x + 13 + 3 = 16x
10x + 16 = 16x
Subtract 10x from both sides of the equation to simplify:
10x + 16 - 10x = 16x - 10x
16 = 6x
Divide both sides by 6 to simplify:
6x = 16
\(x = \frac{16}{6}\\x = \frac{8}{3}\)

Answer:
117 in²
Finding the area of the trapezoid:
First, we need to find the area of the trapezoid formed by the dotted lines. The formula for finding the area of the trapezoid is "(a₁ + a₂)h/2".
[Where, a₁ = shorter parallel side; a₂ = longer parallel side]
⇒ (a₁ + a₂)h/2 = Area of trapezoid
⇒ (14 + 26)15/2 = Area of trapezoid
⇒ Area of trapezoid = (40)15/2 = (20)15 = 300 in²
Reviewing on how to find the area of the unshaded region:
To find the area of the shaded region, we need to subtract the area of the unshaded region from the area of the trapezoid. In this case, the unshaded region is a triangle whose base is 26 inches. To find the area of the triangle, we need to use the formula 1/2 x Base x Height. We are given the base, but the height is unknown.
Determining the height:
We are given a small side length "6 inches" and the height of the trapezoid "15 inches". If we subtract the small side length from the height of the trapezoid, we will obtain the height of the triangle.
⇒ Height of trapezoid - Small side length = Height of triangle
⇒ 15 - 6 = Height of triangle
⇒ 9 in = Height of triangle
Determining the area of the unshaded region:
Now, let's substitute the base and the height in the formula to find the area of the triangle
⇒ 1/2 x Base x Height
⇒ 1/2 x 26 x 9
⇒ 13 x 9
⇒ 117 in²
Determining the area of the shaded region:
Finally, let's subtract the area of the unshaded region from the area of the trapezoid to obtain the area of the shaded region.
⇒ Area of trapezoid - Area of unshaded region = Area of shaded region
⇒ 300 - 117 = Area of shaded region
⇒ 183 in² = Area of shaded region

Rich is attending a 4-year college. As a freshman, he was approved for a 10-year, federal unsubsidized student loan in the amount of $7,900 at 4.29%. He knows he
has the option of beginning repayment of the loan in 4.5 years. He also knows that during this non-payment time, interest will accrue at 4.29%.
If Rich decides to make no payments during the 4.5 years, the interest will be capitalized at the end of that period.
a. What will the new principal be when he begins making loan payments?
b. How much interest will he pay over the life of the loan?
a) The new principal (principal + capitalized interest) when Rich begins making loan payments will be $9,425.10.
b) The total interest that Rich will pay over the life of the loan is $4,914.20.
How is interest on student loans determined?The interest on student loans is based on simple interest.
The only interest capitalized is the interest during the non-payment period if the student does not pay the interest.
Some students elect to pay the interest during the non-payment period to reduce the capitalized interest and principal during the payment period.
Capitalization refers to the addition of interest to the principal amount.
Period of student loan = 10 years
The amount of the federal unsubsidized student loan = $7,900
Interest rate = 4.29%
Capitalized interest during the non-payment time = $1,525.10 ($7,900 x 4.29% x 4.5)
New principal when Rich begins making loan payments = $9,425.10 ($7,900 + $1,525.10)
Total interest for loan = $4,914.20 ($7,900 x 4.29% x 14.5)

What is the measure of QPR
Answer:
The answer I got was 86.
Step-by-step explanation:
This is called the central angle theorem. This means that the central angle, which in this case is QOR (let the origin (middle) be O), is twice the size of the inscribed angle, which is QPR.
That means: 2 x QPR = QOR
→ 2 * (x-33) = x + 20
→ 2x - 66 = x + 20
Collect the like terms
→ 2x - x = 20 + 66

A straight angle is 90° since a circle has 360 equal degrees. We'll just take into account angles between 0° and 360° for the time being; however, we'll take into account angles higher than 360° and negative angles later, in the section on trigonometric functions.
Minutes and seconds can be used to further split degrees, but this separation is less common than it once was. Minutes are the 60 equal pieces that make up each degree.

(round your answers to four decimal places.) a typical amount poured into a short, wide glass is ml. a typical deviation from the mean amount poured is ml. (b) the mean amount poured into a tall, slender glass for individuals asked to pour 44.3 ml (1.5 ounces) was 51.3167 ml. what do the values of the means for the two types of glasses suggest about the shape of glasses used? the mean amount for a short, wide glass is ---select--- the mean amount for a tall, slender glass. this suggests that individuals tend to pour ---select--- into a short, wide glass compared to a tall, slender glass.
The values of the means for the two types of glasses suggest about the shape of glasses used is 22ml on average.
When it comes to pouring drinks, bartenders are expected to pour a specific amount of liquid into each glass. However, there may be some variation in the amount poured depending on the shape of the glass. In this scenario, we have data on the actual amount poured by bartenders into a short, wide glass when asked to pour 44.3 ml. We will use this data to calculate the mean and standard deviation and interpret their values.
The mean is the average amount poured into the short, wide glass. To find the mean, we add up all the amounts poured and divide by the number of samples. Using the data provided, we get a mean of 57.889 ml, rounded to three decimal places.
However, the mean doesn't tell us the whole story. We also need to consider the standard deviation, which tells us how much the amounts poured vary from the mean.
To calculate the standard deviation, we first need to find the variance. We calculate this by subtracting the mean from each amount poured, squaring the differences, adding them up, and dividing by the number of samples minus one. Using the data provided, we get a variance of 479.716 ml², rounded to three decimal places.
To get the standard deviation, we take the square root of the variance. Using the data provided, we get a standard deviation of 21.904 ml, rounded to three decimal places.
Interpreting the values of the mean and standard deviation, we can say that a typical amount poured into a short, wide glass is 57.889 ml, while a typical deviation from the mean amount poured is 21.904 ml. This means that the amounts poured vary by about 22 ml on average, which could be due to differences in pouring technique or the shape of the glass.

Step-by-step explanation:
Translation, Reflection and Rotations does not change the size of the figure. As we can see, quadrilateral A'B'C'D' is bigger than the original ABCD, so an enlargement is needed.
The answer is Enlargement, reflection over the y-axis. (C)
The index of refraction of the core of a typical fiber optic is ncore = 1.46; the cladding has nclad = 1.4. calculate the critical angles for the total internal reflection icrit and crit .
Critical angle for the total internal reflection icrit, β = 78.28⁰
Critical angle for the total internal reflection crit, α = 17,22⁰
We have the refractive index of core, \(n_c_o_r_e\) = 1.46
We have the refractive index of clad , \(n_c_l_a_d\) = 1.4
Critical angle can be defined as the incidence angle which results in the refraction angle being equal to at that angle of incidence.
For Total Internal Reflection to occur, the incidence angle must be greater than the critical angle.
We know that the critical angle, θ is given by:
sinθ = \(\frac{n_c_l_a_d}{n_c_o_r_e}\)
sinθ = \(\frac{1.4}{1.46}\)
sinθ = 0.959 = sin⁻¹(0.979) = 78.28⁰
β = θ = 78.28⁰
Now, for α:
\(\frac{sin(90-\alpha )}{sin\alpha } = \frac{1}{n_c_o_r_e}\)
sinα = sin(90⁰-78.28⁰) × 1.46
sinα = sin(11.72⁰) × 1.46
α = sin⁻¹(0.296)
α = 17,22⁰

Critical angle for total internal reflection icrit β = 78.28⁰
Critical angle for total internal reflection crit, α = 17.22⁰
The critical angle can be defined as the angle of incidence at which the angles of refraction are equal to angle of incidence.
The angle of incidence must be greater than the critical angle for total internal reflection to occur.
The refractive index of the core is ncore = 1.46.
The refractive index of clad is nclad = 1.4.
We know that the critical angle, θ is given by:
sinθ = nclad/ ncore
sinθ = 1.4/1.46
sinθ = 0.959
sin⁻¹(0.979) = 78.28⁰
β = θ = 78.28⁰
Now, for α:
sin(90- α) / sin α = 1 / ncore
sinα = sin(90⁰-78.28⁰) × 1.46
sinα = sin(11.72⁰) × 1.46
α = sin⁻¹(0.296)
α = 17.22⁰
Critical angle for icrit β = 78.28⁰
Critical angle for crit α = 17.22⁰
